Abstract
In this paper, three benzothiazole-Schiff bases, 2-([benzothiazol-2-ylimino]
methyl)phenol (L1), 2-([benzothiazol-2-ylimino]methyl)-4-chlorophenol (L2),
and 2-([benzothiazol-2-ylimino]methyl)-4-bromophenol (L3), were environmentally
friendly prepared using a microwave assisted synthesis. These synthesized
ligands were used to chelate Cd (II) to produce three nano-sized solid
complexes, which were characterized using TEM, FT-IR, and XRD. Then three
developed spectrophotometric approaches for ultra-trace quantification of
divalent cadmium have been investigated and the sensitivity of these developed
methods was enhanced using micellar medium. The influence of the type
and amount of buffer, pH, type of surfactant, and amount of ligand during
quantification of cadmium ion were monitored and determined. The calibration
curve was valid over the concentration ranges of 1.0–9.0, 1.1–12.0, and
1.5–14.9 μg mL1 of Cd (II) with detection limits of 0.407, 0.313, and
0.453 μg mL1 using L1, L2, and L3, respectively. The described approaches
had been effectively applied for Cd (II) ion quantification in some water
samples.
